Objective: The purpose of this research was to observe the content of phytochemical compound and antioxidant activity of yellow velvetleaf fruit (Limnocharis flava) extract. Methods: Research consisted of several stages, including sampling, sample preparation, sample extraction, calculation of yield extract, phytochemical analysis (flavonoids, steroids, alkaloids, saponins, and triterpenoids), and antioxidant activity assessment using 2’,2’-diphenyl-1-picrylhydrazyl and iron-reducing power method. Results: The n-hexane and methanol extract contained flavonoids, saponins, and triterpenoids, while flavonoids and triterpenoids were detected on ethyl acetate extract. The IC50 of yellow velvetleaf extract with n-hexane, ethyl acetate, and methanol was 3321.67 ppm, 1439.24 ppm, and 96.0 ppm, respectively. The methanol extract had the highest iron-reducing power with the average absorbance of 0.588 followed by the ethyl acetate extract with the average absorbance of 0.195 and n-hexane extract had lowest with the average absorbance of 0.171. Conclusion: The best solvent to extract the yellow velvetleaf and have highest antioxidant activity was methanol solvent.

This study aimed to determine the effect of emprit ginger powder (Zingiber officinale var. Amarum)  on the characteristic of sweet orange peel herbal tea (Citrus sinensis L.) as well as the appropriateness of emprit ginger powder for the best characteristic. This study was designed using an experimental method which is Completely Randomized Design with the treatment of adding emprit ginger powder (0%, 5%, 10%, 15%, 20%) that was repeated  3 times  to obtain 15 experimental units. Observed variabels were water content, extract water content, vitamin C, total phenolic, total flavonoid, antioxidant activity, scoring test, and hedonic test. The obtained data were analyzed by using the analysis of variance. If it had a significant effect, it was continued to be tested by using the Duncan Multiple Range Test. The results showed that the addition of  emprit ginger powder had a very significant effect on the water content, vitamin C, total phenolic, total flavonoid, antioxidant activity, aroma (scoring and hedonic test), taste (scoring and hedonic test), and overall acceptance, while extract levels in the water had a significant effect and color (hedonic test) had a non significant effect. Furthermore, it showed that the addition of 20% emprit ginger powder extract was the best treatment with the characteristic as follows: 8.13% w / w water content, 26.93% w / d extract water content, vitamin C 25.56 mg / g tea powder, total phenol 17.86 mg GAE / g tea powder, total flavonoids 1.17 mg QE / g tea powder, and antioxidant activity 56.89%. The characteristics of the tea brewing water involves the distinctive aroma of ginger emprit which is very liked, the color is liked, the taste is not bitter and liked, and overall acceptance is liked.

Abstract It is being considered to pyrolyze lignin-rich biomass samples (hazelnut shells, HSs) into bio-fuels and chemicals to solve energy shortages and environmental concerns, volatile products (including liquid products and gas products) were produced and characterized from HSs pyrolysis at 400–1000 °C. With the temperature increases, the maximum output of liquid products was up to 35.79% produced at 700 °C, gas products yields increased from 21.82 to 55.46%. Gas chromatography and mass spectrometry (GC–MS) study indicated that liquid products from HSs riched in phenolic compounds, exceed 42% of liquid products and increased as the temperature rises. The application experiment showed that HSs liquid products had a significant role in antioxidant activity, and revealed that not limited to phenols, all compounds containing phenolic hydroxyl structure act as antioxidant. Composition analysis of gas products showed that more combustible gases were produced at the higher temperature, resulted in the significant increase in gas products higher heating value (HHV) from 6.21 to 24.36 MJ/kg.

Background: Litsea angulata is a plant species belonging to Lauraceae family that is distributed throughout Indonesia, Malaysia, and New Guinea. The seeds have been traditionally used by local people in Kalimantan, Indonesia for the treatment of boils; however, there is no information about the potency of its branch, bark and leaves yet. This study aimed to determine the antioxidant, antimicrobial activity as well as the phytochemical constituent of Litsea angulata branch, bark, and leaves. Methods: Extraction was performed by successive maceration method using n-hexane, ethyl acetate, and ethanol solvent. Antioxidant activity was evaluated by DPPH radical scavenging assay. The antimicrobial activity using the 96 well-plate microdilution broth method against Staphylococcus aureus and Streptococcus mutans. Results: Based on the phytochemical analysis, it showed that extract of L. angulata contains alkaloids, flavonoids, tannins, terpenoids, and coumarin. The results showed that all extracts of plant samples displayed the ability to inhibit DPPH free radical formation and all tested microorganisms. Conclusions: L. angulata contains secondary metabolites such as alkaloids, flavonoids, tannins, terpenoids, carotenoids, and coumarin. The antioxidant activity on different plant extracts was a range as very strong to weak capacity. All extracts in this study could inhibit the growth of S. aureus and S. mutans.

Oxidative stress and inflammation are interlinked processes. The aim of the study was to perform a phytochemical analysis and to evaluate the antioxidant and anti-inflammatory activities of ethanolic Mahonia aquifolium flower (MF), green fruit (MGF), and ripe fruit (MRF) extracts. Plant extract chemical composition was evaluated by HLPC. A DPPH test was used for the in vitro antioxidant activity. The in vivo antioxidant effects and the anti-inflammatory potential were tested on a rat turpentine oil-induced inflammation, by measuring serum nitric oxide (NOx) and TNF-alpha, total oxidative status (TOS), total antioxidant reactivity (TAR), oxidative stress index (OSI), 3-nitrothyrosine (3NT), malondialdehyde (MDA), and total thiols (SH). Extracts were administrated orally in three dilutions (100%, 50%, and 25%) for seven days prior to inflammation. The effects were compared to diclofenac. The HPLC polyphenol and alkaloid analysis revealed chlorogenic acid as the most abundant compound. All extracts had a good in vitro antioxidant activity, decreased NOx, TOS, and 3NT, and increased SH. TNF-alpha was reduced, and TAR increased only by MF and MGF. MDA was not influenced. Our findings suggest that M. aquifolium has anti-inflammatory and antioxidant effects that support the use in primary prevention of the inflammatory processes.

Orange peel is the main by-product from orange juice industry. It is a known source of bioactive compounds, mostly phenolic compounds, and it has been widely studied for its healthy activities. Thus, this research focuses on the establishment of ultrasound-assisted extraction of phenolic compounds in orange peel using a sonotrode. For this purpose, a Box–Behnken design of 27 experiments was carried out with four independent factors—ratio ethanol/water (v/v), time (min), amplitude (%), and pulse (%). Quantitative analyses of phenolic compounds were performed and the antioxidant activity was measured by ABTS and DPPH methods. The validity of the experimental design was confirmed by ANOVA and the optimal sonotrode extraction conditions were obtained by response surface methodology (RSM). The extracts obtained in the established conditions were analyzed by High Performance Liquid Chromatography (HPLC) coupled to mass spectrometer detector and 74 polar compounds were identified. The highest phenolic content and antioxidant activity were obtained using 45/55 ethanol/water (v/v), 35 min, amplitude 90% (110 W), and pulse 100%. The established method allows an increment of phenolics recovery up to 60% higher than a conventional extraction. Moreover, the effect of drying on phenolic content was also evaluated.
